Just setup my Roli - quick and easy. Setup Wii controller no problem. Wifi is good and I can do the sample movements like dance and wave. All charged up. I have the ports setup as instructed and I entered the port summary. For the life of me I cant get the robot to move with ARC or the wii remote . I've used the Roli sample project and saved it as a new name. I'm sure I've missed something that is very simple but I can't seem to figure it out. Any suggestions?
Any help is greatly appreciated - can't wait to see it move!
Thanks - Steve
Jeremie - That is what I figured - I just looked on your web site and see that you sell these for $14.99. Not too bad. However, it is going to cost over $20 for shipping by DHL(!). I see also that you have other distributors - can you recommend one in the US that carries this H-Bridge?
Thanks for your help! And to everyone else, always check your wiring before turning your robot on!
Thanks again! Jeff
@Jeramie,
Since this came mis-wired from the factory, wouldn't it be a warranty claim? (or @jwheat058, are you saying you had the red and black reversed on the EZ-B, so it was reversed polarity).
If it is not a warranty claim, I have a spare one I will sell you for list + USPS shipping cost (~$5 for priority mail). I'll replace it next time I have a larger order from EZ-B that will absorb the shipping costs.
If you want to go that route, my email address is in my profile. I accept Paypal, Amex Serve, or Google Wallet for ePayments.

Alan - I plugged in the red/black wire coming from the H-Bridge to the EZ-B backwards (pos D0), so if that killed my H-Bridge, then it was my fault and will gladly accept your kind offer to sell me one. However, the aforementioned red wire was attached to the H-bridge 3-pos terminal block at the "+5" terminal when I received it. A few posts up, it was pointed out that it should have been attached to the "VCC" terminal. I moved the red wire to that terminal and it still does not work, so I must have done something bad... The button next to that 3-pos terminal block is in the down position.
Thanks for your help! Jeff
Got the payment and H-bridge will be in the mail Friday (maybe tomorrow if I have a small box at home).

Thanks, Alan - I hope that was the problem... Can't wait to get my Roli Rollin'!
BTW, this is going in a Lunar display at a children's science center... I think they will like it! Jeff
Update: Received the H-bridge from Alan (Thank-you, Alan!), installed it and now I'm up and running! Very excited! The only thing is that the H-bridge that Alan sent me was slightly larger than the original one, so it won't mate up to the mounting holes. I will probably just hot-glue it in the cavity there to keep it from bangin' around - no one will see it... Anyway, thanks to all of you for your help and suggestions!
That was a very easy mistake to make. It would be nice if there was some sort of prevention for us polarity-challenged bozos - maybe a diode or something?
Now on to calibrating my servos!
